Multipurpose case

ABSTRACT

Disclosed is a multipurpose case used as a case of cosmetic tools or stationery materials which allows withdrawal of cosmetic tools or stationery materials as required by a user. The multipurpose case has a simple structure and a core accommodated in the multipurpose case may be withdrawn at once. The multipurpose case includes a core fixing section, to which first and second tubes are coupled from upper and lower portions thereof. A third tube is arranged between the first and second tubes and the core fixing section is coupled to a lower end of the third tube. When the third tube is moved up, the core fixing section is simultaneously moved up, so that the core provided at an upper end of the core fixing section is easily withdrawn to an exterior. The multipurpose case having the simple structure reduces the manufacturing cost and improves the convenience of use by allowing for easy withdrawal of the core.

TECHNICAL FIELD

The present invention relates to a multipurpose case, more particularlyto a multipurpose case used as a housing of a cosmetic tool, such as abrush set including a lip brush and a blusher brush, or used as ahousing of a ball-point pen, a color pencil, a blade, a gimlet, and apastel crayon, capable of allowing slidable withdrawal of the aboveelements at once while having a simple construction.

BACKGROUND ART

In general, various kinds of brushes are widely available for cosmeticuse. The brushes are comprised of a bar and a brush member or eyelinerformed at one end of the bar. The brushes are stored in a brush bagwithout a case.

For example, as shown in FIG. 1, the brush includes a bar SC made ofmetal and a brush member Br such as a blusher brush or eyeliner fixedlyformed at one end of the bar SC. A plurality of brushes are stored in abrush bag (not shown). A user selectively uses the brush for making-upthe face of the user and stores the brush again in the brush bag aftercompleting the making-up.

However, the brush member fixed at one end of the bar is exposed to anexterior, so it is inconvenient for the user to carry the brush. Inaddition, cosmetic powder sticking to the brush member may contaminatean interior part of the brush bag. Furthermore, the brush member iseasily damaged when it makes contact with other objects, so the lifespan of the brush member is shortened.

FIG. 2 shows a lip liner, which is a kind of conventional cosmetic tool.As shown in FIG. 2, the lip liner includes an upper case 1 formed at aninner portion thereof with a plurality of linear guide slots 2, a corefixing section 103 formed at one end thereof with a guide protrusion 6for allowing the core fixing section 103 to move along the linear guideslots 2 and formed at the other end thereof with a engagement protrusion7 having a spiral protuberance 9, and a lower case 3 formed at an innerportion thereof with a spiral groove 4.

In the figure, the lip liner core 8 (lip liner pencil) is verticallyinserted into an upper portion of the guide protrusion 6 and theengagement protrusion 7 formed at a lower end of the guide protrusion 6is inserted into the lower case 3 so that the spiral groove 4 is meshedwith the spiral protuberance 9. In addition, the guide protrusion 6 isengaged with the linear guide slot 2 formed in the upper case so thatthe guide protrusion 6 may be moved up and down linearly.

When using the lip liner, a user firstly rotates the body 100 of the lipliner while manually gripping the upper case 1. At this time, theengagement protrusion 7 having the spiral protuberance 9 moves up alongthe spiral groove 4 so that the core fixing section 103 moves up.

If the core fixing section 103 moves up, the lip liner core 8 fixed tothe guide protrusion 6 of the core fixing section 103 is linearly movedup due to the guide protrusion 6 engaged with the linear guide slot 2.

The downward movement of the lip liner core 8 is the reverse of theupward movement of the lip liner, so it will not be further describedbelow.

As mentioned above, the conventional lip liner structure includes ashort spiral protrusion formed at an outer portion of the core fixingsection 103 and a long spiral slot formed at an inner portion of thelower case 3. Such a lip liner structure is not only used for lipliners, but also used for other cosmetic tools or stationery materials.

However, it is very difficult to form the spiral slots in the innerportion of the lower case, so the productivity of the lip liner islowered. In addition, it takes a long time to assemble the lip liner.

A multipurpose case 10 of the present invention is divided into upperand lower parts as shown in the drawings.

Referring to FIG. 3, the multipurpose case 10 of the present inventionmainly includes a case 100 and a core fixing section 200 formed at anupper end thereof with a core 228 (pencil) and slidably moved up anddown within the case 100.

A first supporting section 110 is formed at a lower portion of the case100 and a stepped portion 111 is formed at a lower portion of the firstsupporting section 110. A first tube 101 having a predetermined lengthis coupled to an outer surface of the first supporting section 110. Thefirst tube 101 is fixed to the stepped portion 111.

A pair of connection members 120 are vertically installed on an upperportion of the first supporting section 110 and engagement protrusions121 are integrally formed at an inner portions of the connection members120 in order to fix a guide member 210.

A second supporting section 130 is formed at upper ends of theconnection members 120. An outer diameter of the second supportingsection 130 is smaller than a distance between the connection members120, which are vertically extend from the upper portion of the firstsupporting section 110. A second tube 102 is arranged around the secondsupporting section 130.

The second supporting section 130 is divided into two partscorresponding to the connection members 120, and a perforation hole 131is formed at a center of the second supporting section 130. Due to theperforation hole 130 formed at the center of the second supportingsection 130, a vertical member 220 of the core fixing section 200 iseasily assembled into the case 100 and easily moved up and down.

The guide member 210 is formed at a lower portion of the core fixingsection 200. The guide member 210 is installed at an upper portion ofthe first supporting section 110. Guide slots 211 are formed at bothsides of the guide member 210. The connection members 120 areaccommodated in the guide slots 211 so that the core fixing section 200can be vertically moved up and down.

Engagement slots 212 to be engaged with the engagement protrusions 121of the connection members 120 are provided in the guide slots 211 formedat both sides of the guide member 210 so as to prevent the core 226 frombeing downwardly moved.

An outer diameter of the guide member 210 is smaller than the distancebetween the connection members 120, which are vertically installed onthe upper portion of the first supporting section 110, so a third tube201, into which the guide member 210 is inserted, can be moved upwardswithout being interrupted with the connection members 120.

The vertical member 220 is vertically formed at a center of the guidemember 210 and a supporting member 230 is provided at an upper end ofthe vertical member 220. A core supporting member 225 is coupled to thesupporting section 230 so as to prevent the core 226 from being moved.

In addition, a lid is can be coupled to an outer peripheral portion ofthe third tube 201 as required by a user.

Although the multipurpose case 10 shown in FIG. 3 has a cylindricalshape, it can be modified into another shapes. According to otherembodiments of the present invention, the multipurpose case 10 may havea triangular sectional shape, a polygonal sectional shape or an ovalsectional shape.

Hereinafter, an assembling process and an operation of the multipurposecase 100 will be described with reference to FIGS. 4A to 5B.

Referring to FIG. 4A, the vertical member 220 of the core fixing section200 is positioned in the perforation hole 131 by widening a spacebetween two parts of the second supporting section 130, which isintegrally formed with the connection members 120 vertically installedon the upper portion of the first supporting section 110.

At this time, the connection members 120 are arranged in match with theguide slots 211 of the guide member 210 in such a manner that the guidemember 210 moves up and down along the connection members 120. Then, thefirst tube 101 is coupled to an upper portion of the first supportingsection 110.

In addition, as shown in FIG. 4B, the second tube 102 is coupled to anupper end of the second supporting section 130 so as to prevent twoparts of the second supporting section from being separated from eachother.

Then, as shown in FIG. 4C, the third tube 201 is assembled around theguide member 210 such that the third tube 201 surrounds the first andsecond tubes 101 and 102, which are coupled to the first and secondsupporting sections 110 and 130, thereby completing the assemblingprocess.

Hereinafter, the operation of the multipurpose case 10 will be describedin detail with reference to FIGS. 5A and 5B.

Firstly, in order to withdraw the core 226 accommodated in the corefixing section 200, a user grips the first tube 101 of the case 100shown in FIG. 5 using one hand, and rotates the third tube 201 bygripping an upper portion of the third tube 201 using the other hand.Thus, as shown in FIG. 5B, the core fixing section 200 coupled to alower end of the third tube 201 is protruded into an upper portion ofthe second tube 102 so that the user can use the core 226 provided atthe upper end of the core fixing section 200.

At this time, since the guide slots 211 formed at both sides of theguide member 210 are engaged with the connection members 120, the guidemember 210 can be vertically guided between the connection members 120.In addition, while the guide member 210 is vertically guided, theengagement slots 212 formed in the guide slots 211 can be engaged withthe engagement protrusions 121 of the connection members 120, therebypreventing movement of the guide member 120 during use of the core 226.

On the other hand, the multipurpose case can be used as a case ofcosmetic tools and stationery materials, if the user exchanges the core226 of the core supporting member 225 with a color pencil, a pastelcrayon, solid paste, a lip brush, an eye brush and a blusher brush.

FIG. 6 shows a multipurpose case 10 according to another embodiment ofthe present invention used as a case of a ball-point pen, in which thecore 226 fixed in the core fixing section 200 is a pencil of theball-point pen. The structure of the multipurpose case 10 shown in FIG.6 is identical to the structure of the multipurpose case 10 shown inFIG. 3 except for a pencil supporting hole 226 a formed at a center ofthe core fixing section so as to support the core (pencil) 226.

The pencil supporting hole 226 can be easily fabricated through adie-casting process by modifying a shape of a mold.

That is, the multipurpose case according to the present invention can beused as a case of stationery materials, such as a ball-point pen, ablade, and a gimlet, and as a case of cosmetic tools, such as a brushset.

FIGS. 7A to 8B are views showing various embodiments of the presentinvention, where various kinds of cores 226 are provided in themultipurpose case depending on the various shapes of the core supportingmember 225. Referring to FIGS. 7A to 8B, cores 226 are stored in themultipurpose case when they are not used and withdrawn from themultipurpose case for use.

Since the core 226 is hidden in the multipurpose case or protruded fromthe multipurpose depending on an operation of the core fixing section200, which is slidably moved up and down within the case 100, themultipurpose case can be safely stored in a bag without contaminatingthe bag. In addition, the core is prevented from making contact withanother objects when it is stored in the bag, so the life span of thecore can be extended. The multipurpose case of the present invention canbe used for a case of a brush, a blade and a gimlet, while improving thereliability thereof.

FIG. 9 is an exploded perspective view showing a multipurpose caseaccording to another embodiment of the present invention, FIG. 10 is aside sectional view of the multipurpose case shown in FIG. 9 when themultipurpose case is in a state of being assembled, and FIG. 11 is aside sectional view of the multipurpose case when a core is withdrawnfrom the multipurpose case.

According to the present embodiment, the multipurpose case includes acore 600 having various sectional shapes including triangular,rectangular, polygonal, and oval shapes, an upper body 718 and a lowerbody 722. In addition, the multipurpose case includes a core fixingsection 700 formed at an upper portion thereof with the core 600 andmoving the core 600 up and down so as to withdraw the core 600 out ofthe multipurpose case, a fixing member 800 accommodating the core fixingsection 700 therein and guiding the core fixing section 700 when thecore fixing section 700 moves up and down, a middle case 500, which isarranged around the fixing member 800 and to which the core fixingsection 700 is fixed such that the core fixing section 700 is moved upby using one hand of a user, a lower case 900 accommodating the middlecase 500 therein, and an upper lid 400.

Hereinafter, a case used for a cosmetic tool will be described indetail.

When sectional shapes or external appearances of the upper lid 400 andthe lower case 900 are formed in a predetermined shape, such astriangular, rectangular, polygonal, and oval shapes, it is preferred toform the core 600 in a predetermined shape corresponding to the shapesof the upper lid 400 and the lower case 900.

In the present embodiment shown in FIGS. 9 to 11, the multipurpose casehas a cylindrical shape.

The core fixing section 700 includes the upper body 718 formed with aplurality of fixing holes 716 and the lower body 722 verticallyextending from a lower portion of the upper body 718 and formed at bothlower sides thereof with wings 720.

The middle case 500 has a cylindrical shape and is formed at an upperperipheral portion thereof with a plurality of slits 514. The slits 514are provided to prevent the middle case 500 from being slid from user'shand when the user pushes the middle case 500.

The fixing member 800 is formed at both sides thereof with guide slots824, into which the wings 720 of the core fixing section 700 areinserted in order to slidably moved up and down along the guide slots824.

A plurality of engagement protrusions 832 are formed at one side of theguide slots 824. Preferably, 3 to 5 engagement protrusions 832 areprovided in the guide slots 824. In this case, the wings 720sequentially make contact with the engagement protrusions 832 while thecore fixing section 700 is being moved up and down so that the movementof the core fixing section 700 is periodically stopped.

In addition, as compared with the conventional spiral protrusion orspiral slots, the guide slots 824 can be easily fabricated.

An upper fixing cap 510 is fixedly inserted into the upper lid 400. Atouch part 512 is formed at a lower portion of the upper fixing cap 510.The touch part 512 is protruded radially inwards so that a vacuum isformed in the fixing member 800 when the touch part 512 makes contactwith an outer peripheral portion of the fixing member 800.

It is preferred to prevent air or moisture from penetrating into thefixing member 800 by allowing the touch part 512 to make contact withthe upper end of the fixing member 800. By forming the vacuum state inthe case, the core is prevented from being solidified with properlymaintaining wet in the core.

The touch part 512 has a semi-circular sectional shape and is preferablyprotruded radially inwards. However, it is possible to form the touchpart 412 in various shapes, such as a polygonal shape or an oval shape,adapted for the case.

Preferably, the touch part 512 is made of rubber or silicon.

A filling hole 830 is formed at a center of a lower fixing cap 828 and astepped portion 826 is formed at a lower portion of the lower fixing cap828. The fixing member 800 is vertically installed on the steppedportion 826.

According to the multipurpose case having the above structure, the guideslots 824 of the fixing member 800 can be formed in a long size. Thus,manufacturing and assembling processes of the multipurpose case are veryconvenient. In addition, the user can withdraw the core using one hand,so it is very convenient for the user to use the multipurpose case.

The conventional case for cosmetic tools and stationery materials isrequired to have formed a long spiral slot at an inner portion of thecase so as to withdraw the core in a long size. For this reason, thecase is required to have a relatively long size so as to form the longspiral slot therein. However, it is very difficult to form a long spiralslot in the inner portion of the case. On the contrary, the multipurposecase of the present invention can be slidably moved along the guideslots formed in the fixing member in a simple manner, so that theproductivity of the multipurpose case can be improved.

In addition, it is well known to those skilled in the art that upper andlower parts of the multipurpose case of the present invention can besymmetrically formed.

The core fixed to the core fixing section 700 is soft solid material andis exchanged with various kinds of cores, such as a pastel crayon, asolid paste, a perfume pen, a fountain pen, a brush pen, an eye liner, amascara, and a lip stick.

This is possible by forming the guide slots at both sides of the fixingmember 800 in a long size.

INDUSTRIAL APPLICABILITY

As can be seen from the foregoing, the multipurpose case according tothe present invention has a simple structure so an assembling processthereof is simplified, so the productivity thereof is improved without afaulty assembly occurring. In addition, manufacturing cost of themultipurpose case can be reduced.

In addition, it is convenient for a user to withdraw the core from themultipurpose case.

Furthermore, the core is hidden in the multipurpose case when it is notused, so a bag storing the multipurpose case is prevented from beingcontaminated and the core is prevented from making contact with otherobjects so the life span of the core is expanded.

In addition, the multipurpose case can be widely used as a case ofcosmetic tools and stationery materials.
